The work of preparing International Standards is normally carried o

17、ut through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO c

18、ollaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International

19、 Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elemen

20、ts of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1833-24 was prepared by Technical Committee ISO/TC 38, Textiles. This first edition, together with ISO 1833-1 to ISO 1833-23, cancels and replaces ISO 1833:19

30、SO 1833-24:2010(E) ISO 2010 All rights reserved 1Textiles Quantitative chemical analysis Part 24: Mixtures of polyester and certain other fibres (method using phenol and tetrachloroethane) WARNING This part of ISO 1833 calls for the use of substances/procedures that may be injurious to the health/en

31、vironment if appropriate conditions are not observed. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety/environment at any stage. 1 Scope This part of ISO 1833 specifies a method using phenol and tetrachloroethane to determine

32、the percentage of polyester after removal of non-fibrous matter, in textiles made of binary mixtures of certain polyester fibres with acrylic, polypropylene or aramid fibres. This method is not applicable to coated fabrics. 2 Normative references The following referenced documents are indispensable

33、for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1833-1:2006, Textiles Quantitative chemical analysis Part 1: General principles of testing 3 Princ

34、iple The polyester fibre is dissolved out from a known dry mass of the mixture, with a reagent composed of phenol and tetrachloroethane. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage

35、of polyester is found by difference. 4 Reagents and apparatus Use the reagents described in ISO 1833-1, together with those specified in 4.1 and 4.2. 4.1 Phenol and tetrachloroethane mixture: the reagent mass ratio is 6:4. SAFETY PRECAUTIONS The harmful effects of this reagent shall be borne in mind

36、, and full precautions shall be taken during use. The treatment with this reagent shall be carried out in fume cabinet or hood. 4.2 Ethanol.

37、 apparatus, suitable for maintaining the temperature of the conical flask at (50 2) C (for example, water bath with thermostat). 6 Test procedure Follow the general procedure described in ISO 1833-1, and then proceed as follows. Place the specimen in the conical flask. Add 100 ml of phenol and tetra

38、chloroethane mixture (4.1) per gram of specimen. Shake the conical flask for 10 min at (50 2) C, then decant the liquid through the weighed filter crucible using suction. Add a further 100 ml of phenol and tetrachloroethane mixture, warmed up to (50 2) C, and decant the liquid through the filter cru

39、cible. Filter the contents of the conical flask through the weighed filter crucible (ISO 1833-1:2006, 6.1) and transfer any residual fibres to the crucible by washing out the residue from the conical flask with 100 ml of ethanol. Repeat the same washing operation with 100 ml of ethanol. Drain the cr

40、ucible under suction and wash the residue on the filter once with water. Do not apply suction again until the washing liquor has drained under gravity. Finally, drain the crucible under suction, dry the crucible and residue, then cool and weigh them. 7 Calculation and expression of results Calculate

41、 the results as described in the instructions in Clause 10 of ISO 1833-1:2006. The value of d is 1,00.
